IMPROVE einen.

To ALL WHOM 1T MAY ooNoERN.:

A:Be it known that I, SAMUEL A. CHAPMAN, of Waterbury, in the county of New Haven, and State of Connecticut, have' invented n new anduseful Improvement in Hinges, of which the following is'a lfullyclear, and exact description,referencebeing had to theiaccompanying drawing, forminggpart of this specification, and

in which- 4 Figure-1 represents an endriew of a butt-hinge constructed according to my improvement, Figure-2 a transverse section of the same, i Figure 3 an inner or under view thereof, Figure 4-face views ot' blanks used in covering the hinge`in accordance with my improvement, and Figure5 a transverse section of a modification of such improved hinge or mode of lapping its covering. My invention consistsin encasing hinges ni'ade of iron in sheet-brass wrappers, in such manner a s that the latterare immovably and s ecurelyconnected n'ithfthe former, andi-cover and prevent exposure ot' the iron or interior body ofthe cased hinge; also, said invention consists in burring or sinkingthe brass wrappers into the vscrew-holesof the hinge, for the more perfect attainment ofthe objects specified.

A Referring to the accompanying drawing, A and B represent thetn'o sections or halves of a butt-hinge, the bodies a of .whch are of iron, as may be also the joint-pin c. These bodies forming, when united, an iron hinge, I encase, before fitting them together, in sheet-brass wrappers m m', by, say, taking blanks s. s, suitably cut and shaped, `as represented, for instance, in fig.'4, to form, on suitably bending the blanks over the faces, longitudinal edges and knuckles of the hinge, and lapping tliernasrat d, or at e, in tig.` 5, a sheathing or coverA ing'to such portions of the hinge, and, it may be, securing` the same" by solderinglat the ends and corners, in connection with end-strips or pieces,f, ofsheet brass. To further prevent exposure of the'iron, and to secure or holdthe'sheebbrass wrappers to their places, after o r during theprocess of bonding and pressing the blanks on the iron bodies Ato formsvrappers, b urr or puncture,`and` sink theportions of the sheet brass, covering the screw-holes g, into the latter, as clearly exhibited in gs..2 and 5', thus forming a close and securely brass- `wrapped ironthing'e, equal for all purposes to a solid brasshinge, but made at materially less cost, by reason of the di'erence in prieebetween brass and iron; i

By this method of encasingthe parts of a hinge ina sheet-brass wrapper o r wrappers, there is'no necessity for filing up and polishing the surface of the iron, as in plating and soldering, or galvanizing; it is therefore a. less expensive operationrwhilst a heavier 'andmore durable covering is obtained. f

'Whatl here claim, and desire to secure by Letters Patent, is l l. 'An iron hinge wrapped .or covered en its edges and Afaces with sheet brass, substantially as described. 2.' In iron hinges' encased by sheet-brass `wrappers, barring orv sinking said wrappers into the screw-holes ofthe hinge, for the double purpose of preventing exposure of the iron, and' of holding-or securing the wrappers, essentially'as specified.
